#### Defining a Clipping Plane

From the Edit menu, point to Graphic Display Window, and choose Lighting, Materials. Click the Clip Planes tab.

You need only two pieces of information to define your clipping plane: an XYZ location and an IJK vector. The IJK vector points in the direction of what remains visible.

There are two ways to define this information:

- You can click on your part in the Graphic Display window, and Planner takes the point that you clicked as the clipping plane's location. Once you click a location, Planner automatically enables your clipping plane and sets the vector to the surface normal at the location. You can then modify the IJK vector as desired.

- You can select the Enabled check box and then manually type in the XYZ location and IJK vector.

The XYZ and IJK values are in the active part alignment coordinate system and not the CAD coordinate system.

The Flip IJK button flips the vector so that it points in the opposite direction.

Once you have your clipping plane modified to where you want it, click Apply to see your changes. Planner hides all portions of your part model pointing away from your chosen clipping plane vector.

Clearing the Enabled check box disables the current clipping plane. Disabled clipping planes have a yellow color. The ability to place and move your clipping plane is also disabled. Enabled clipping planes have a red color.

You can define multiple clipping planes by selecting a new clipping plane option button and then following the above instructions.
